RUDOLPH G. WINTER, OF MILWAUKEE, WISCONSIN.

HINGE.

Specioaton of Letters Patent.

Application led June 27, 1914. Serial No. 847,575.

To all fwwm it may concern Be it known that I, RUDOLPH G. VINTER, of Milwaukee, VWisconsin, have invented a Hinge, of which the following is a specification.

This invention relates to detachable hinges, that is tosay hinges consisting of two parts, detachable one from the other, one of which is secured to the door-jamb and the other to the door, whereby the door may be removed from the casing by a simple lifting or other like movement. Y

The object of the invention is to produce a hinge especially adapted for light doors, such ,as screen-doors', storm-doors, etc., which can be cheaply manufactured and will be strong and substantial in use and fully reversible so that the same hinge can be used for either right-hand or left-hand doors, or doors swung in any manner.

My invention comprises two essential elements, namely, first, the'hinge proper, one leaf of which is provided with meansV for permanently fixing it to the door; and secondly, a hollow slotted member mounted on the casing with which the other leaf of the first member is formed to engage by sliding it into suitable sockets in said second member, and which then houses and protects said engaging parts.

More specifically my invention may best be understood by reference to the following detailed description, taken in connection with the accompanying drawing', wherein- Figure 1 is a front elevation of the hinge with the two sections interlocked; Fig. 2 is a transverse section thereof on the plane 2, showing also portions of the door and casing to which it is attached; Fig. 3 is a transverse section of the hinge on the plane 3, with portions of the door and casing; Figs. 4f and 5 are perspective views of the two members of the hinge separated, from the rear or inner side; Fig. 6 is a side elevation of the second member of the hinge separately, with the interengaging portions of the rst member in position therein,cbe

, ling a section on the plane 6; and Fig. 7 is a longitudinal section through the same on the plane 7. v

The vhinge comprises the two members A and B, the first of which is intended to be .attached to door and the ascend te.

the casing or jamb thereof, D. rlhe member A -is itself composed of the two leaves E and F, which are pivoted together by the pintle G, the leaf E having formed on its pivoted edge the pivot lugs el and e2, and the leaf F on its pivoted edge the pivot lugs f1, f2 and f3, through all of which the pintle G passes. It will be noted that the lug c1 is narrower than the space between the two lugs f1 and f? and that the lugs c2 and f3 have mutually engaging oblique faces, whereby as the leaf E swings about the leaf F in either direction it is raised relatively thereto so that the gravity of lthe'door acting'on the oblique faces produces an imf pulse tending to swing it shut, and this impulse is moreover assisted or increased by one of the two springs H1, H2, which, as will be seen, are symmetrically disposed and coiled in opposite directions, so that when Vthe leaf E swings in one direction the spring H1v acts to lclose it, the spring H2 remaining neutral, and when the leaf E swings in the other direction the spring H2 becomes active and the spring H1 remains neutral. Although this hinge maybe usedfor a doubley swinging door it is primarily intended to be used on single-swinging doors, but the provision of the two opposite springs 1s made in order that the vhinge may act equally well whichever way the door is swung. Now theV peculiarit'y of these springs is that they have a double action, that is to say act both torsionally and compressionally; for inasmuch as they completely lill the space between the lugs c2 and f2 when the door swings, so that the leaf E is raised relative to the leaf F, the springs will be longitudinally compressed and thereby exert together a downward pressure upon the oblique faces of the lugs c2 and f2, thus acting to close the door in this way as well as by the Ypreviously described torsional action of one of the springs. Now in lorder both to assist the torsional force by removing torsional friction from the pintle and also to assist the compressive force by relieving the pintle of endwise friction, and also to prevent buckling of the springs, I further pro-- vide a short sleeve I upon the pintle in the center of the space between lugs c2 and f2, upon which sleeve the adjacent ends of the 'two springs E? and E? are closelyeoile'd as isataatea oet; si, 191e.

shown. (The lower spring H1 is omitted in Fig. 4 to show this sleeve.) It will be seen that this sleeve provides a correctly formed bearing surface upon the pintle which can receive and hold a lubricant so as to relieve the frictiony as well as to prevent any buckling of the springs.

The leaf E of the member A is provided with screw-holes c3 adapted to receive screws e, whereby the leaf is secured to the door C, and in order further to make the hinge fully reversible it will be seen that the fiat portion of the leaf is disposed in the axial plane on the pintle and a liner or shim J is inserted between it and the door. IThe other leaf F is provided with means for engaging it with member B, said meansl comprising a pair of horizontally extending Yas tongues ft, each of which has at its base on one side (this being always the under side) a notch or recess f5. The member B consists of a sheet of metal having its four edges, b1, Z22, 3 and b4, turned at right angles so as to form a rest against the face of the casing and protect the depressed tongues b5 which are within the boX so formed from contact-with the casing. The side Z22 which lies neXt to the edge 0f the door is preferably provided with one or more pointed projections b, which are pressed into the casing when the member is attached and Vprovide an additional hold thereto. The face of the member B is also provided with screw-holes If, through which pass screws 58, iixing it permanently to the casing.

In the flange b2 on the side nearest the edge of the door are formed two slots b9, which are of the same width as the thickness of the tongues f4 and of a greater length than the width of the latter. Coperating with these slots b9, the tongues b5 are formed by cutting out three sides thereof from the face of the member B and pressing them inwardly a. suiicient distance to allow the tong-ues f* to slide neatly between them and the face of the member B, as clearly illustrated in Fig. 7. It will be seen that these -tongues b5 aredisposed oppositely or symmetrically to one another, thus making the member B fully reversible so that it can be used with either side up indifferently.

The members being separated as shown in Figs. et and 5 are readily vengaged by sliding the tongues f4 into the slots b9 until they pass under the tongues b5 and until the edge of the body of the member F comes up against the edge of the member B, whereupon the door being released, the member F `is pulled down by gravityA until the notches f5 engage over the abutments or lower edges of the slots b9, and the door is thus held firmly in position until it is desired to detach it again, which is done by simply raising theV door sufficiently to disengage the notches f5 from the lower edges of Y the slots b2 and pulling the member F out of engagement with the member B.

1While I have herein above shown the most improved form of my invention, I wish it understood that not all of the features are essential thereto or necessarily made in the exact form shown, but various changes and modifications in the constructions as herein shown may be made without departing from the spirit of my invention, and I wish it understood therefore that the latter is not otherwise limited than by the scope of my Y low structure adapted to besecured to aV door casing, and having a slot in one of its edges through which-said tongue is insertible to lie wholly within and be housed"by\ said other member, and said notch being adapted to engage the lower edge of said slot by gravity acting on said door to bring same into normal position.

2. A detachable Yhinge comprising two members, one of said members consisting of two leaves pivoted together, one of said leaves being adapted to be secured to a door and the other of said leaves having a tongueprovided with a notch on its under edge, theY other of said members comprising a piece of sheet metal having a flanged edge and iadapted to be secured to a door casing, and having a slot in said flanged edge through which said tongue vis adapted to pass, said notch being adapted to engage the lower edge of said Vslot by gravity acting on said door to bring same into normal position, and said other member being provided with a depressed tongue formed from its face, be-V tween which and said face the end of said tongue on the first member is-ada-pted toV pass and iirmly lie.

3. A hinge provided with two hinge leaves Y and a pintle, said leaves'having pivotrlugs through which said pintle passes, two of said lugs having oblique coperating faces whereby one of said leaves in turning on the pintle is moved longitudinally thereon, there being an open space on the pintle between one of said two lugs on one of said leaves f and the neXt one of the remaining lugs on the other ofrsaid leaves, and a' pair of oppositely wound and symmetrically'disposed I coiled springs mounted onsaid pintle in said open space and lling the latter longitudi-` nallyl ofsaid pintle and each having its ends respectively engaging said hinge leaves, whereby said springs act both torsionally and compressionally to return the swinging leaf and door connectible thereto to closed position Jfrom either direction.

4. A hinge provided with two hinge leaves and a pintle, said leaves having pivot lugs through which said pintle passes, two of said lugs having oblique cooperating faces whereby one of said leaves in turning on the pintle is moved longitudinally thereon, there being an open space on the pintle between one of said two lugs on one of said leaves and the next one of the remaininglugs on the other of said leaves, and a pair of oppositely wound and symmetrically disposed coiled springs mounted on said pintle in said open space and filling the latter longitudinally of said pintle and each having its ends respectively engaging said hinge leaves, whereby said springs act both torsionally and compressionally to return the swinging leaf and door connectible thereto to the closed position from either direction,

and a bearing sleeve on said pintle having the adjacent ends of saidI springs coiled thereon. n

5. A detachable hinge comprising two members, one of said members consisting of two leaves pivoted together, one of said leaves being adapted to be fixed to a door and the other of said leaves having a tongue provided with a notch on its under edge, the other of said members comprising a hollow structure adapted to be secured to a door casing, and having an opening in one of its sides and an abutment, through which opening said tongue is insertible to lie wholly within and be housed by said other member, and said notch being adapted to engage said abutment by gravity acting on said door to bring same into normal position.

ln witness whereof I have signed my name in the presence of two witnesses.
